Vitamin C Serum

1 tsp. Vitamin C powder {L-Ascorbic Acid}
1 tsp. Distilled water
1 tsp.glycerin

Dissolve Vitamin C in water, mashing down all clumps to make a smooth liquid solution.  Dissolve completely, you do not want a grainy serum. Add glycerin and combine well.
Serum is ready to use. Use within 1 week because Vitamin C is very unstable and breaks down quickly. Thusfore, serum loses it's properties after a week. Store in dark place, as light causes the Vitamin C to break down as well.
